Ok, now I see that you are trying to find a palette to put gouache in. As everyone around here has suggested in the past, this is a bad idea to do so. After gouache dries (and it DOES dry, no matter what these palette manufacturers claim), when it rewets it's like sludge (thick watercolor), not like like the thick opaque paint it once was. So, what you're trying to do, won't work with good results. You either should get with you tubes, or buy travel jars, like these: https://www.amazon.com/gp/product/B086JXYLF8/ These won't dry out your paint.
